It’s stuck on here. Anybody knows this answer ?
There is very little to go on, not your fault.
First stab is that Unix (macOS) networking is very fragile and any DNS problem can cause a bad day. This recovery needs a solid network to use with solid DNS...
Second stab, does your network connection have any firewalls on it that block ports? I would recommend a wide open for outbound connections network with just a simple Network Address Translator (NAT) setup.
